Description
The Seiko 5 Sports SRPG35K1 is a modern interpretation of the classic military field watch, combining robust mechanical engineering with understated tactical styling. Housed in a 39mm brushed stainless steel case, this automatic timepiece features a commanding black dial with oversized Arabic numerals and luminous hands for exceptional legibility in all conditions. The day-date display at 3 o'clock adds practical functionality, while the beige nylon NATO-style strap ensures durability and comfort for everyday wear.
At the heart of this timepiece beats the Seiko Caliber 4R36 automatic movement, a workhorse mechanism offering both automatic winding and manual winding capability. With a 41-hour power reserve and proven reliability, this movement represents Seiko's commitment to accessible mechanical watchmaking. The see-through caseback allows you to observe the intricate ballet of gears and springs that power this instrument, a feature typically reserved for higher-priced timepieces.

FAQ
Q: Does this watch require battery changes?
A: No. The SRPG35K1 is powered by the Seiko Caliber 4R36 automatic movement, which winds itself through the natural motion of your wrist. It also features manual winding capability via the crown. As a fully mechanical watch, it never requires battery replacement.
Q: How long will the watch run if I don't wear it?
A: When fully wound, the 4R36 movement provides a 41-hour power reserve. If you remove the watch on Friday evening, it will still be running on Sunday morning. You can also manually wind it using the crown to ensure it stays powered.
Q: Is the NATO strap easily replaceable?
A: Yes. The beige nylon NATO-style strap can be easily changed without tools. The watch features standard 20mm lug width, making it compatible with a wide variety of aftermarket straps including leather, rubber, and other NATO-style options.
Q: Can I swim or shower with this watch?
A: With 100-metre water resistance, the SRPG35K1 is suitable for swimming and recreational water activities. However, we recommend avoiding hot showers, saunas, and operating the crown underwater, as temperature changes and steam can compromise the seals over time.
Q: What does the exhibition caseback show?
A: The see-through caseback reveals the working movement inside, allowing you to observe the oscillating rotor that winds the mainspring, along with the bridges, gears, and jewels of the 4R36 caliber. It's a fascinating view into mechanical watchmaking.
Q: How accurate is this automatic movement?
A: The Seiko 4R36 movement typically runs within +45 to -35 seconds per day, which is standard for automatic movements in this price range. Accuracy can be affected by wearing habits, position, and temperature. The movement can be regulated by a watchmaker if desired.
Q: Is this watch suitable for smaller wrists?
A: At 39mm in diameter, the SRPG35K1 is considered a versatile size that wears comfortably on most wrists. It's smaller than many modern sports watches, making it an excellent choice for those who prefer a more classic proportioned field watch that doesn't overwhelm the wrist.
Warranty
- Manufacturer Warranty: This Seiko watch is covered by a 3-year international warranty from the date of purchase when purchased from an authorised retailer.
- Coverage: The warranty covers manufacturing defects in materials and workmanship under normal use conditions.
- What Is Not Covered: Normal wear and tear, scratches to the case or crystal, strap or bracelet wear, damage caused by accident or misuse, water damage resulting from improper use or failure to ensure the crown is secured, damage from unauthorised repairs or modifications, and loss or theft.
- Battery Exclusion: As this is an automatic mechanical watch, no battery is present. However, any servicing or maintenance not related to manufacturing defects is excluded from warranty coverage.
- Authorised Retailer Requirement: This warranty is only valid when the watch is purchased from an authorised Seiko retailer such as Cassims & Co. Proof of purchase is required for all warranty claims.
- Warranty Service: For warranty service, please contact Cassims & Co. with your original proof of purchase. We will facilitate all warranty claims directly with Seiko.

Care guide
- Daily Wear: Avoid impacts, shocks, and extreme temperatures. Remove the watch during high-impact sports or activities involving heavy machinery.
- Winding: If the watch has stopped, manually wind it 20-30 times clockwise using the crown at the 3 o'clock position. Daily wear should provide sufficient automatic winding.
- Water Resistance: Ensure the crown is pushed fully in before any water exposure. Never operate the crown or pushers while the watch is wet or submerged.
- Cleaning: Wipe the case and crystal with a soft, lint-free cloth. For deeper cleaning, use a slightly damp cloth with mild soap, then dry thoroughly. The nylon strap can be hand-washed with mild detergent and air-dried.
- Strap Care: Nylon NATO straps are durable but should be kept clean and dry when possible. Rotate with alternative straps to extend longevity. Replace if fraying or excessive wear is observed.
- Magnetic Fields: Avoid prolonged exposure to strong magnetic fields from speakers, mobile phones, magnetic clasps, and electronic devices, as this can affect timekeeping accuracy.
- Storage: When not wearing the watch for extended periods, store it in a cool, dry place away from direct sunlight. Consider using a watch winder if you own multiple automatic watches.
- Servicing: We recommend professional servicing every 3-5 years to maintain water resistance, lubricate the movement, and ensure optimal performance. Cassims & Co. offers expert servicing for all Seiko timepieces.
- Crystal Care: The Hardlex mineral crystal is scratch-resistant but not scratchproof. Avoid contact with abrasive surfaces. Minor scratches can be polished by a professional watchmaker.
